Discrete Uniform

Discrete uniform distribution.

Usage

var discreteUniform = require( '@stdlib/stats/base/dists/discrete-uniform' );

discreteUniform

Discrete uniform distribution.

var dist = discreteUniform;
// returns {...}

The namespace contains the following distribution functions:

  • cdf( x, a, b ): discrete uniform distribution cumulative distribution function.
  • logcdf( x, a, b ): evaluate the natural logarithm of the cumulative distribution function for a discrete uniform distribution.
  • logpmf( x, a, b ): evaluate the natural logarithm of the probability mass function (PMF) for a discrete uniform distribution.
  • mgf( t, a, b ): discrete uniform distribution moment-generating function (MGF).
  • pmf( x, a, b ): discrete uniform distribution probability mass function (PMF).
  • quantile( p, a, b ): discrete uniform distribution quantile function.

The namespace contains the following functions for calculating distribution properties:

The namespace contains a constructor function for creating a discrete uniform distribution object.

var DiscreteUniform = require( '@stdlib/stats/base/dists/discrete-uniform' ).DiscreteUniform;

var dist = new DiscreteUniform( 2, 4 );

var y = dist.pmf( 3, 0 );
// returns ~0.333

Examples

var objectKeys = require( '@stdlib/utils/keys' );
var discreteUniform = require( '@stdlib/stats/base/dists/discrete-uniform' );

console.log( objectKeys( discreteUniform ) );
